RESEARCH ON THE CD ADSORPTION CAPABILITY OF BIOCHAR GENERATED FROM THE BARK OF ACACIA PLANTS IN A WATER ENVIRONMENT
Keywords:Bio char produced from acacia shell, Aqueous medium, capacity, Cd, Pb
This paper focuses on studying the effect of pH and time on Cd adsorption capacity in aqueous medium of bio char produced from acacia shell. The results show that pH has an effect on the Cd adsorption capacity of acacia shell bio char which is calcined at different temperatures. The Cd adsorption capacity of them increased sharply when the pH of the solution is increased from 5 to 6. When the pH is increased from 6 to 8, the Cd adsorption capacity is almost unchanged. And in the experimental period from 5 minutes to 60 minutes, the longer the sample shaking time, the higher the Cd adsorption capacity.
